Re: TI-H: REAL radio-link




IS it possible to have one line modulate the amplitude and the other 
line modulate frequency. Then have a frequence counter and a level meter 
test the frequency and amplitude. never mind, I just realized why that 
would not work! 

New idea: Could a crystal generate a frequency high enough that the data 
can be multiplexed fast enough to avoid missing data???

What about 4 separate frequencies SendTip, SendMid, RecTip, RecMid. You 
could have a switch to select whether your calc is 1 or 2. It is a 
little less "automatic", but by having the calcs set differently, you 
could send the data on two frequencies and recieve it on four 
frequencies. Maybe a little plug could be added, or dip switches used to 
select or switch crystals! You would carry two of the same crystal, and 
let the person you want to trancieve data with borrow one, or have 
several preset frequencies inside set by a switch. It would be VERY 
dificult to manualy tune it with a knob or something like that.
